ORA-04030/ORA-12500 In 32 Bit Windows Environment

One of our production db we are getting frequently the following error and our end user not able to connect database server.

ORA-04030: out of process memory when trying to allocate 2097196 bytes (joxp heap,f:OldSpace)

When Search on metalink I found the following note

Doc ID:
Note:373602.1

I didn't follow the above metalink note suggest solution. but for the workaround I bounce the db and increase the Processes parameter. after that error is gone.
